The new Samsung Galaxy S 4G was launched on feb 23th for 199 after 50 mail in rebate. We believe this is a little higher. The Galaxy S 4G is very similar to the existing Samsung Vibrant, a popular Android phone. It has the same 1-GHz Cortex-A8 processor, runs Android 2.2 on a similar 4-inch Super AMOLED screen, and has the same 5-megapixel camera.
Cnet just review the Samsung Galaxy S 4G .
The good: The Samsung Galaxy S 4G has 4G connectivity, a front-facing camera for video calls, and a larger battery. Android 2.2 offers impressive data speeds and good call quality. Other highlights include a rich and vibrant Super AMOLED touch screen and a 5-megapixel camera with 720p HD video recording.
The bad: No camera flash. The Galaxy S 4G has less internal memory than the Vibrant. There was some slight sluggishness with some tasks.
The bottom line: The Samsung Galaxy S 4G is a fantastic Android smartphone for T-Mobile customers, delivering fast data speeds and other improvements, but Vibrant owners should be fine holding off for now.
